Answer:
0.54 is the sales tax.
Step-by-step explanation:
2.25 x 3 = 6.75
When trying to do percentages move the decimal place to the right 2 times.
6.75 x 0.08= 0.54.
Answer:
x=3 and y=2
Step-by-step explanation:
The pythagorean triples are generated by two integrers x and y that can be found by solving the following system of equations:
![\left \{ {{x^{2}-y^{2}=5}\atop {2xy=12}} \atop {x^{2}+y^{2}=13}}\right.](https://tex.z-dn.net/?f=%5Cleft%20%5C%7B%20%7B%7Bx%5E%7B2%7D-y%5E%7B2%7D%3D5%7D%5Catop%20%7B2xy%3D12%7D%7D%20%5Catop%20%7Bx%5E%7B2%7D%2By%5E%7B2%7D%3D13%7D%7D%5Cright.)
Solve the system of equations, and we get that the solution is x=3 and y=2.
Therefore, the combination of integrers that ca be used to generate the pythagorea triple are: x=3 and y=2
